这份报纸论述方法由压电的生成器从沥青人行道收获机械精力。结果证明在沥青人行道的势能能每公里每小巷直到 150 kW/h。机械精力的部分能被压电的变换器收获。七个典型变换器的表演通过有限元素分析被检验。PZT 堆的结果表演并且多层，在沥青人行道环境的钗钹和桥罐头工作。PZT 堆积并且多层更高让精力变换评价。然而，如果这些变换器在人行道直接被嵌入，全部的收获精力是小的。一个原型人行道发电机用 PZT 堆积被开发增加收获精力。发电机能在交通拥挤下面从人行道收获超过 50 kW/h 精力。816 PZT 堆积为一个发电机被推荐。圆形状被建议让 PZT 堆积减少应力的集中。并且多层的结构被推荐因为 PZT 堆发电机的电的潜力到减少。生成器能在沥青人行道作为传感器被扩大，它能被用来监视交通，人行道压力和温度。

英文摘要：

This paper presents the way to harvest mechanical energy from asphalt pavement by piezoelectric generator. Results show that the potential energy in asphalt pavement can be up to 150 kW/h per lane per kilometre. Part of the mechanical energy can be harvested by piezoelectric transducers. The performance of seven typical transducers is examined through finite element analysis. Results show that PZT piles and multilayer, cymbal and bridge can work in asphalt pavement environment. PZT piles and multilayer have higher energy converting rate, However, the total harvested energy is small if these transducers are embedded directly in pavement. A prototype pavement generator is developed using PZT piles to increase the harvested energy. The generator can harvest more than 50 kW/h energy from the pavement under heavy traffic. 8-16 PZT piles are recommended for one generator. Round shape is suggested for the PZT piles to reduce the concentration of stress. And multilayer structure is recommended for PZT piles to decrease the electric potential of generator. The generator can be extended as sensor in the asphalt pavement, which can be used to monitor the traffic, pavement stress and temperature.
